Say au revoir to the Old World—the newest French day spas look as good as they make you feel. In Paris, the ultra-modern Le 32 Montorgueil Spa Nuxe (32 Rue Montorgueil; 33-1/55- 80-71-40) is housed in a 12th-century wine warehouse. Masterminded by cosmetologist Aliza Jabès, owner of Nuxe beauty products, the spa conducts treatments in caves and tunnels. Try the "phytochoc," an exfoliating massage with cocoa beans (an anti-aging cure). • In the hills of Mougins, the Shiseido Spa at Le Mas Candille (Blvd. Clément-Rebuffel; 33-4/92-28-43-53) specializes in facials combined with qi pressure-point massages. To enhance the experience, each treatment room has its own bamboo-walled meditation garden. • Nice's HIP (2 Rue Longchamp; 33-4/93-16-00-20) is a futuristic refuge of soft blue light and lavender blooms. Right angles are noticeably absent in the immaculate but inviting all-white rooms. HIP uses its own line of flower-extract oils, as well as a miracle substance called Oramel, which exfoliates and imparts an otherworldly glow to the face and body.
